As a response to customer needs, the BTA drilling machine built a transfer line in which it integrated not only deep hole drilling but also the twist drilling of cross lubrication holes and the deburring of the cross holes at the entry to the deep hole drilled central hole. Thread cutting is done at another station. Finally, the holes are rinsed, i.e. the remaining chips are washed out and the remaining cooling lubricant is blown off. The cycle time to be achieved required the use of four machining spindles per station.

At the BTA drilling machine was designed for fully automatic, unattended operation, an automation element (EPU), i.e. a workpiece pallet reloading system, was integrated. The machine is operated by using the Siemens 810D CNC control system and remote diagnostics and checking is facilitated via a tele-service from our plant.
